BackgroundThe incidence of psychotic disorders s elevated in some minority ethnic populations. However, we know little about the outcome of psychoses in these populations.AlmsTo investigate patterns and determinants of long-term course and outcome of psychoses by ethnic group following a first episode.methodSOP-10 is a 10-year follow-up of an ethnically diverse cohort of 532 individuals with first-episode psychosis identified in the UK. Information was collected, at baseline, on clinical presentation and neurodevelopmental and social factors and, at follow-up, on course and outcome.ResultsThere was evidence that, compared with White British, Black Caribbean patients experienced worse clinical, social and service use outcomes and Black African patients experienced worse social and service use outcomes. There was evidence that baseline social disadvantage contributed to these disparities.ConclusionsThese findings suggest ethnic disparities in the incidence of psychoses extend, for some groups, to worse outcomes in multiple domains.

BackgroundStudies of the impact of mental disorders on educational attainment are rare in both high-income and low- and middle-income (LAMI) countries.AimsTo examine the association between early-onset mental disorder and subsequent termination of education.MethodSixteen countries taking part in the World Health Organization World Mental Health Survey Initiative were surveyed with the Composite International Diagnostic Interview (n=41 688). Survival models were used to estimate associations between DSM–IV mental disorders and subsequent non-attainment of educational milestones.ResultsIn high-income countries, prior substance use disorders were associated with non-completion at all stages of education (OR 1.4–15.2). Anxiety disorders (OR=1.3), mood disorders (OR=1.4) and impulse control disorders (OR=2.2) were associated with early termination of secondary education. In LAMI countries, impulse control disorders (OR=1.3) and substance use disorders (OR=1.5) were associated with early termination of secondary education.ConclusionsOnset of mental disorder and subsequent non-completion of education are consistently associated in both high-income and LAMI countries.

BackgroundLittle is known about the epidemiology of adult attention-deficit hyperactivity disorder (ADHD).AimsTo estimate the prevalence and correlates of DSM-IV adult ADHD in the World Health Organization World Mental Health Survey Initiative.MethodAn ADHD screen was administered to respondents aged 18–44 years in ten countries in the Americas, Europe and the Middle East (n=11422). Masked clinical reappraisal interviews were administered to 154 US respondents to calibrate the screen. Multiple imputation was used to estimate prevalence and correlates based on the assumption of cross-national calibration comparability.ResultsEstimates of ADHD prevalence averaged 3.4% (range 1.2–7.3%), with lower prevalence in lower-income countries (1.9%) compared with higher-income countries (4.2%). Adult ADHD often co-occurs with other DSM-IV disorders and is associated with considerable role disability. Few cases are treated for ADHD, but in many cases treatment is given for comorbid disorders.ConclusionsAdult ADHD should be considered more seriously in future epidemiological and clinical studies than is currently the case.
